DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3 The utility model provides a technical solution: a front and rear vehicle body sleeve structure, comprising a first tube body 1 and a second tube body 11, the ends of the first tube body 1 and the second tube body 11 are respectively provided with a first connecting end 12 and a second connecting end 13, a limiting ring 17 at the other end of the first tube body 1 is clamped in a slide groove 18 opened on the inner side of the second tube body 11 and fixed by a limiting bolt 19, by providing the first tube body 1 and the second tube body 11 which are sleeved with each other, and with the cooperation of the limiting ring 17, the slide groove 18 and the limiting bolt 19 and other structures, the relative lengths of the two tube bodies can be adjusted according to needs and fixed by the limiting bolt 19, the overall pipe fitting can be adjusted to a suitable length to adapt to different installation requirements, and the application range of the equipment is effectively expanded.
[0018] The opening ends of the first tube body 1 and the second tube body 11 are both provided with a limiting mechanism, wherein the limiting mechanism comprises a positioning ring 22 , and the inner side of the positioning ring 22 is connected with a guide ring 24 via a spring 23 .
[0019] In the above solution, the side of the second connection end 13 is connected with a flange 14. The side of the flange 14 is connected to the mounting mechanism through a connecting piece.
[0020] In the above solution, the bottoms of the first connection end 12 and the second connection end 13 are fixed to the connection block 16 through the support column 15, and a connection hole is provided on the connection block 16. The connection block 16 can be fixed to the corresponding connection device by screws to effectively fix the sleeve mechanism.
[0021] In the above scheme, the first tube body 1 and the second tube body 11 are respectively provided with a first reinforcement layer 2 and a second reinforcement layer 21. The first reinforcement layer 2 and the second reinforcement layer 21 are made of hard polymer materials, which effectively improve the wear resistance and connection strength of the pipe fittings, and are used to wrap and install the internal lines for protection. By arranging the first reinforcement layer 2 and the second reinforcement layer 21 inside the first tube body 1 and the second tube body 11, the structural strength of the tube body can be effectively enhanced, and the wear resistance of the sleeve mechanism can be improved, thereby improving the protection effect of the internal wiring harness.
[0022] In the above solution, the guide ring 24 is a silicone rubber ring. The guide ring 24 is squeezed by the multiple springs 23 inside the positioning ring 22, so that the guide ring 24 can contact the outside of the line, thereby achieving a stable guiding effect.
[0023] In the above solution, the end grooves of the first connection end 12 and the second connection end 13 are filled with airbags 25. The arrangement of the airbags 25 enhances the compressive strength of the first connection end 12 and the second connection end 13, and increases the effective supporting weight of the device.
[0024] In the above scheme, an elastic conical positioning ring 26 is arranged inside the limiting mechanism, and the opening diameter of the conical positioning ring 26 is larger than the outlet diameter. The limiting mechanism composed of the positioning ring 22, the spring 23 and the guide ring 24 arranged inside the first tube body 1 and the second tube body 11 can guide and initially limit the wire harness, and the conical positioning ring 26 arranged later can fix the wire harness in the conical positioning ring 26 under its elastic action, so as to achieve the sealing of the wire harness, prevent external dust from entering the sleeve from the gap, and improve the protection performance of the equipment.
[0025] Working principle:
[0026] When using this kind of automobile front and rear body sleeve structure, the length of the sleeve structure is first adjusted as needed. The user can adjust the relative length of the two tube bodies as needed and fix them through the limit bolts 19, so that the overall pipe fitting can be adjusted to a suitable length to adapt to different installation requirements. After that, the connecting block 16 can be fixed to the corresponding connecting device through screws to achieve effective fixation of the sleeve mechanism, and the corresponding wiring harness is introduced into the sleeve through the opening of the first tube body 1. During this process, the guide ring 24 is squeezed under the action of multiple springs 23 on the inner side of the positioning ring 22, so that the guide ring 24 can contact with the outer side of the line, thereby achieving a stable guiding effect, and under the action of the conical positioning ring 26 with good elasticity, the outer wall of the wiring harness can be in close contact with the inner wall of the conical positioning ring 26, thereby achieving the sealing of the wiring harness, preventing external dust from entering the sleeve from the gap, and effectively improving the installation quality of the sleeve structure.
